UNHAlRlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 677,425, dated July 2, 1901.

Application filed October 22,1900. Serial No. 33,857. (No model.)

To ctZZ whom it 777/661] concern:

Be itknown that I, JOHN G. ROTHE, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Unhairiug-Machines, of which the following is a specification.

This invention relates to an improved unl1airing;machine designed to cut the waterhair near its root out of the wool in a quick and effective manner.

The machine is more particularly designed for unhairing rabbit-skins, but may of course be also used upon other pelts.

In the accompanying drawings, Figure 1 is a plan of my fmproved unhairing-machine. Fig. 2 is a vertical longitudinal section on line 2 2, Fig. 1; Fig. 3, a frontelevation of the machine. Figs. 4 and 5 are sections through the front end of the machine, showing the parts in different positions. Fig. 6 is a detail of the brush-actuating cam, and Fig. 7 a detail of the mechanismfor operating the lower shearing-blade.

The letter Ct represents the frame of the machine, upon which is free to reciprocate a slide 12, to which motion is imparted from power-shaft c by cams c, engaging the rollers b of the slide. The slide b carries an endless apron d, to which the pelts A to be unhaired are secured and which is advanced slightly for each complete reciprocating movement of the slide. The apron cl passes around the forward pointed end 17' of the slide, under guideroller b Fig. 2, over feedroller 6, around feed-roller 19 under guide-roller b and over guide-roller 19 The rollers 19 b are mounted in uprights b of the slide 5 and are intergeared by wheels b Z2 Fig. 3. The shaft of the roller 12 carries a ratchet-wheel b, which when the frame 1) passes through the last portion of its backward movement is engaged by a pawl c, mounted upon the frame a. In this way the rollers b b are slightly turned at each complete reciprocating movement of the slide to correspondingly advance the pelts A. The degree of forward movement may be regulated by connecting the pawl e adjustably to frame Ct by means of clamp screw e, Fig. 1. Above the inclined edge b there is secured to the slide 1) a brushf, which is movable with the slide, so as to constantly engage the pelt. Below the edge 12 is arranged a vertically-movable and rotatable brush g, which is adapted to alternately engage and clear the pelt. The brush g is rotated from power-shaft c by belts 9', provided with tension devices g and passing over pulleys h on a counter-shaft h, intergeared with shaft 0 by wheels b 0 The shaft of the brush g is hung in bearings 7i, secured to a pair of rods 2", to which vertically reciprocating movement is imparted by cams 2' engaging the rollers '5 and mounted uponashaft j, Fig. 3. This shaft j is driven from shaft 0 by counter-shaft 7c, intergeared with shafts cj by bevel-gear 7a The brushes f g serve to brush the wool of the pelts backward, so that the stiff waterhair will project forward from the tapering end Z2 of the slide 5, Fig. 4:. This water-hair is engaged and severed by a pair of short upper shear-blades Z, coacting with one common longer shear-blade m. The'upper blades Z are pivoted at their outer ends to the frame a at Z and are at their inner ends connected by pivoted links Z to a vertically-movable slide n. This slide is guided by pins 12 and is reciprocated from shaft j by a cam n Fig. 2, which in this way oscillates the blades Z upon their fulcrums l. The lower blade m is reciprocated vertically by being connected to rods m, provided with pivoted tappets m engaged by cams m of shaft j, Fig. 7. The tappets m are also adapted to be engaged at their upper side by stops or abutments 0, connected with each other by a shaft 0. One of the abutments 0 is provided with a hand-1ever 0 Fig. 2, which has a catch 0 adapted to engage any one of the notches of a fixed segment 0 By adjusting the position of this hand-lever the abutments 0 are raised or lowered, and thus the throw of the tappets m and consequently the play of the blade m, may be readily adjusted. If the abutments 0 are raised to clear the tappets m the motion of the lower blade m will be arrested.

The operation is as follows: The pelts A are pinned or otherwise fastened to the apron d, and as the latter is reciprocated the pelts are intermittently advanced toward the brushes and shears. The upper brush f will turn the hair and wool backward at the top of the apron, While the lower brush Will rise when the apron is in its retracted position, Fig. 4, to turn the wool backward at the bottom of the apron. The stiff Water-hair will project forward between the brushes at the pointed edge of the slide Z), and While the brush 9 descends, Fig. 5, the apron and pelt will be rapidly fed forward, so as to cause the exposed water-hair to be severed by the shears.

The slide then retracts and the apron, together with the pelt, is advanced a short distance by the pawl 6, so as to expose a new row of Water-hairs to the action of the shears at the next forward movement of the slide.

What I claim is 1. In an unhairing-inachine, the combination of a reciprocating slide, with an endless apron supported thereby, means for intermittently feeding said apron, a pair of brushes, a pair of pivoted upper shear-blades, and a vertically-inovable lower shear-blade, substantially as specified.

2. In an unhairing-inachine, the combination of a pair of pivoted upper shear-blades, with a vertically-movable slide, pivoted links for connecting the inner ends of the blades to the slide, and with a vertically-movable lower shear-blade adapted to coact with the nppershear-blades,substantially as specified.

3. In an unhairing-machine, the combination of a pair of pivoted upper shear-blades, with a lower shear-blade, rods that support the lower blade, tappets pivoted to the rods, cams engaging the tappets, and adjustable stops above the tappets,substantially as specifled.

4. In an nnhairing-inachine, the combination of the following elements: a reciprocating' slide, a series of rollers carried thereby, an endless apron engaging the rollers, a pawl and ratchet for intermittently advancing the apron, an upper brush carried by the slide, a vertically-movable rotatable brush below the slide, a pair of pivoted upper shear-blades, and a coacting vertically-movable lower shearblade, substantially as specified.
